Description

14 2 O O G14 2 O O G

Den foreliggende opfindelse angår et stillads med et antal arbejdsniveauer i form af platforme og med mindst én lodret stige, som gør det muligt at klatre til de forskellige arbejdsniveauer, samt med svingbare lemme, der i 5 en hvilestilling er i plan med platformen og i en opsvinget stilling giver adgang ad stigen til platformen.The present invention relates to a scaffold having a plurality of working levels in the form of platforms and having at least one vertical ladder allowing climbing to the different working levels, and with pivotal limbs which in a rest position are flush with the platform and in a the raised position gives access to the ladder to the platform.

Ved et fra svensk fremlæggelsesskrift nr. 389.7o4 kendt stillads af denne art er der risiko for, at personale på stilladset ved et uheld kan falde ned i den langs stigen lo i det indre af stilladset dannede lodrette skakt, når de svingbare lemme er i deres åbne stilling, hvor de giver adgang ad stigen til platformene.With a scaffold of this kind known from Swedish publication no. 389.7o4, there is a risk that personnel on the scaffold may accidentally fall into the vertical shaft formed along the ladder lo in the interior of the scaffold when the pivoting limbs are in their open position where they provide access to the ladder to the platforms.

Formålet med den foreliggende opfindelse er at undgå denne ulykkesrisiko, og dette opnås ifølge opfindelsen ved, 15 at hver lem ved hjælp af vægtstangsarme er forbundet med en bøjle med U-form, hvis ender er lejret vandret på stigens vanger i en sådan position, at den, alt efter om lemmen er i sin nævnte opsvingede· stilling eller sin hvilestilling, indtager henholdsvis en. i det væsentlige vandret hævet stilling, 2o hvor den afspærrer arbejdsniveauet, og en lodret sænket stilling langs stigen, hvor den frigiver arbejdsniveauet.The object of the present invention is to avoid this risk of accident, and this is achieved according to the invention in that each limb is connected by means of lever arms with a U-shape bracket, the ends of which are mounted horizontally on the rails of the ladder in such a position that the one, depending on whether the limb is in its said swung position or its resting position, occupies one. substantially horizontally raised position, 2o where it suspends the working level, and a vertically lowered position along the ladder where it releases the working level.

Den U-formede bøjle danner således et rækværk, som forhindrer adgang til den lodrette skakt dannet langs stigen, når lemmen svinges til sin åbne stilling, således at 25 afspærringen sker automatisk, når der er behov for det. Derimod vil bøjlen være slået ned lodret langs stigen, således at den ikke generer passagen langs platformen, når lemmen er i sin hvilestilling og lukker for adgangen til det underliggende arbejdsniveau.The U-shaped hanger thus forms a guardrail which prevents access to the vertical shaft formed along the ladder when the limb is pivoted to its open position so that the shut-off occurs automatically when needed. By contrast, the shackle will be lowered vertically along the ladder so that it does not interfere with the passage along the platform when the limb is in its resting position, closing access to the underlying working level.

3o Stilladset kan ifølge opfindelsen hensigtsmæssigt væ re udført således, at de nævnte vægtstangsarme forbinder den U-formede bøjle med den kant af lemmen, som vender mod stigen, idet den modsatte kant af lemmen er hængslet.According to the invention, the scaffold may conveniently be constructed such that said lever arms connect the U-shaped brace to the edge of the limb facing the ladder, the opposite edge of the limb being hinged.

Ifølge opfindelsen kan åbningsvinklen for lemmen med 35 fordel være større end 9o° og være begrænset af anslag, hvorved man kan opnå en stabil passende stilling af lemmen og den U-formede bøjle. For at sikre at lemmen ikke falder til- 2 142358 bage mod hvilestillingen under indvirkning af sin egenvægt, kan vægtstangsarmene og den U-formede bøjle ifølge opfindelsen være således anbragt og indrettet, at vægtstangsåbningen under åbningen af lemmen, hvor de bevæges fra sin hvilestil-5 ling til sin opsvingede stilling, passerer en ustabil ligevægtsstilling, hvor de er på linie med lemmen.According to the invention, the opening angle of the limb may advantageously be greater than 90 ° and be limited by impact, thereby providing a stable suitable position of the limb and the U-shaped brace. In order to ensure that the limb does not fall back to the resting position under the influence of its own weight, the lever arms and the U-shaped bracket according to the invention may be arranged and arranged so that the lever opening during the opening of the limb where they are moved from its resting position. 5 ling to its upturned position, an unstable equilibrium position passes where they are aligned with the limb.

I en hensigtsmæssig praktisk konstruktion ifølge opfindelsen er lemmen lejret i en platformdel, der er monteret på stigens trin og på tværstænger i stilladset ved hjælp af lo kroge, der eventuelt er aflåselige.In a convenient practical construction according to the invention, the limb is mounted in a platform part which is mounted on the steps of the ladder and on transverse rods in the scaffold by means of latch hooks which are optionally lockable.

Opfindelsen skal herefter forklares nærmere under henvisning. til tegningen, hvor fig. 1 viser et perspektivisk delbillede af et stillads ifølge opfindelsen omfattende en udførel-15 sesform for lemmen og fig. 2 et skematisk sidebillede, som viser virkemåden af denne lem.The invention will then be explained in more detail with reference to the following. to the drawing, in which fig. 1 is a perspective view of a scaffold according to the invention comprising an embodiment of the limb; and FIG. 2 is a schematic side view showing the operation of this limb.

I fig. 1 er der i perspektiv skematisk vist en del af et stillads rejst langs en væg 1, f.eks. en bygning. Dette 2o stillads omfatter et arbejdsniveau 2, som er dannet af brædder 3, der hviler på tværstænger, der udgør dele af stilladset, og er fastgjort til disse tværstænger.Stivere 4 sikrer krydsafstivningen af stilladset, og ikke viste rækværk sikrer beskyttelsen mod nedstyrtninger på den udvendige side af 25 stilladset. Dette omfatter ligeledes et adgangsrum med vandret i det væsentlige rektangulært eller kvadratisk tværsnit, og hvis udvendige side parallel med væggen 1 er dannet af en lodret stige 5 omfattende vandrette trin 6 med mellemrum, som gør det muligt for en person let at klatre. Den modståen-3o <je side af adgangsrammen kan ligeledes udgøres af stiger 7 med faste eller forskydelige trin, der er forbundet med stigen 5 ved hjælp af tværstænger 8.In FIG. 1 schematically shows in perspective a part of a scaffold erected along a wall 1, e.g. a building. This 2o scaffold comprises a working level 2 formed by boards 3 resting on cross bars forming portions of the scaffold and attached to these crossbars. outside of the 25 scaffold. This also includes an access space of horizontal substantially rectangular or square cross-section, the outer side of which is parallel to the wall 1 formed by a vertical ladder 5 comprising horizontal steps 6 at intervals which allow a person to climb easily. The resistor side of the access frame may also be formed by ladders 7 having fixed or sliding steps connected to ladder 5 by means of cross bars 8.

Platformen 2 strækker sig til begge sider for adgangsrummet, idet den er afbrudt indvendigt i dette rum, 35 således at brædderne 3 vil hvile med den ene ende på tværstængerne 8.The platform 2 extends to both sides of the access room, being interrupted internally in this space, 35 so that boards 3 will rest with one end of the crossbars 8.

I det indre af adgangsrummet og i niveau med platfor- 3 142853 men 2 findes en ydre ramme med rektangulær eller kvadratisk form svarende til formen af adgangsrummet, og som er udført af metalrør eller -profiler. Denne ramme er monteret på trinnene 6 og 11 på stigerne henholdsvis 5 og 7 ved 5 hjælp af kroge 12, som kan være aflåselige.In the interior of the access room and at the level of the platform 2, there is an outer frame of rectangular or square shape corresponding to the shape of the access room and which is made of metal pipes or profiles. This frame is mounted on steps 6 and 11 on ladders 5 and 7, respectively, by means of hooks 12, which may be lockable.

I det indre af rammen er der fastgjort en fast platformsdel 13, på hvis ene side der er lejret en lem 14, f. eks. ved hjælp af hængsler 15.In the interior of the frame is fixed a fixed platform part 13, on one side of which is mounted a limb 14, for example by means of hinges 15.

Denne lem 14 har med fordel sådanne dimensioner, at lo den optager den største del af den indre overflade af den nævnte ramme. Endvidere strækker lemmen 14 sig indvendigt i rammen fra stigen 5 hen til i nærheden af stigen 7, og den er lejret ved hjælp af hængslerne 15 på den faste del 13 langs sin side nærmest stigen 7.Advantageously, this limb 14 has such dimensions that it occupies the largest portion of the inner surface of said frame. Furthermore, the limb 14 extends inside the frame from the ladder 5 to near the ladder 7, and it is mounted by the hinges 15 on the fixed part 13 along its side closest to the ladder 7.

15 Vægtstangsarme 16 forbinder den frie side af lemmen 14 med en bøjle 17 med U-form, hvis to ender er monteret vandret og er svingelige på de lodrette vanger af stigen 5, f.eks. ved hjælp af fastspændingsbøjler 18. Bøjlen 17 .har en størrelse svarende i det væsentlige til størrelsen af 2o lemmen 14 eller lidt større end denne, og den er fastgjort på stigen 5 i en passende højde, f.eks. ca. 1 m. Vægtstangsarmene 16 har en sådan længde, at når lemmen 14 er i sin vandrette sænkede stilling, hvor den lukker for adgangen til det underliggende niveau, er bøjlen 17 og vægtstangsar-25 mene 16 i det væsentlige lodrette og sænket ned imod stigen 5, som vist i fig. 1. Når lemmen 14 er hævet for at gøre det muligt for en person at klatre op eller ned langs stigen, som vist med fuldt optrukket linie i fig, 2, befinder bøjlen 17 sig derimod i en i det væsentlige vandret stil-3o ling og danner således et rækværk omkring den lodrette skakt dannet ved siden af stigen 5. I denne stilling har vægtstængerne 16 passeret en ustabil ligtvægtsstilling, i hvilken de var på linie med lemmen 14, således at denne ikke kan falde tilbage mod stigen 5 under indvirkning af sin egenvægt.Barbell arms 16 connect the free side of the limb 14 with a U-shaped bracket 17, the two ends of which are mounted horizontally and are pivotable on the vertical rails of ladder 5, e.g. by means of clamping brackets 18. The bracket 17 has a size substantially equal to the size of the limb 14 or slightly larger than this one, and it is secured to the ladder 5 at a suitable height, e.g. ca. The lever arms 16 are of such length that when the limb 14 is in its horizontal lowered position where it closes for access to the underlying level, the bracket 17 and the lever arms 16 are substantially vertical and lowered against the ladder 5 , as shown in FIG. 1. When the limb 14 is raised to allow a person to climb up or down the ladder, as shown by the fully drawn line of FIG. 2, the bracket 17, on the other hand, is in a substantially horizontal position and thus forming a railing around the vertical shaft formed adjacent the ladder 5. In this position, the bar 16 has passed an unstable equilibrium position in which they were aligned with the limb 14 so that it cannot fall back against the ladder 5 under the influence of its own weight.

35 Anslag anbragt på hængslerne eller på den faste del 13 begrænser med fordel åbningsvinklen af lemmen 14 til den i fig. 2 viste vinkel.Advantageously, abutments arranged on the hinges or on the fixed part 13 limit the opening angle of the limb 14 to that of FIG. 2.

14 2 8 5 δ 414 2 8 5 δ 4

Lemmen fungerer på følgende måde: Når der ikke er nogen, som benytter adgangsrummet, er lemmen 14 i den vandrette sænkede stilling, vist i fig.The limb operates as follows: When no one is using the access room, the limb 14 is in the horizontal lowered position, shown in FIG.

1, hvor den fuldstændigt lukker adgangsrummet og sikrer en 5 overfladekontinuitet mellem platformene 3 på arbejdsniveau-et 2. Bøjlen 17 og vægtstangsarmene 16, der er sænket lodret ned mod stigen 5, kan ikke genere passagen af personer, som går på arbejdsniveauet 2.1, where it completely closes the access space and ensures a surface continuity between the platforms 3 at the working level 2. The bracket 17 and the lever arms 16 lowered vertically against the ladder 5 cannot interfere with the passage of persons entering the working level 2.

Når en eller anden klatrer på stigen og kommer op til lo umiddelbart under arbejdsniveauet 2, løfter han lemmen 14 og åbner den helt, som vist i fig. 2, hvilket bringer bøjlen 17 i den i fig. 2 viste sikkerhedsstilling. Medens lemmen 14 forbliver åben, spærrer bøjlen 17 således adgangen til stigen 5 for enhver, der befinder sig på arbejdsniveauet 2.When someone climbs the ladder and comes up to lo immediately below the working level 2, he lifts the limb 14 and opens it completely, as shown in FIG. 2, which makes the bracket 17 in the FIG. 2. Thus, while the limb 14 remains open, the shackle 17 blocks access to the ladder 5 for anyone at the working level 2.

15 Det vil ligeledes bemærkes, at en person, som klatrer langs stigen 5, let kan passere under den hævede bøjle 17 for at få fodfæste på platformen 3. Ligeledes har en person, som befinder sig på platformen 3, let adgang til det underliggende niveau ved at passere under bøjlen 17.It will also be noted that a person climbing the ladder 5 can easily pass under the raised hanger 17 to gain a foothold on the platform 3. Similarly, a person who is on the platform 3 has easy access to the underlying level. by passing under the hoop 17.

2o Det skal iøvrigt bemærkes, at lemmene er anbragt på stilladset i alle arbejdsniveauerne, og at de normalt er lukkede. Hvis er person, som befinder sig på et overliggende arbejdsniveau således åbner lemmen 14 for at klatre ned, og hvis han styrter ned i dette øjeblik, vil han falde på ar-25 bejdsniveauet umiddelbart nedenunder, hvor lemmen normalt er lukket. Nedstyrtningen vil således være uden fare.2o It should also be noted that the limbs are located on the scaffold at all levels of work and that they are normally closed. Thus, if a person who is at an overlying level of work opens the limb 14 to climb down, and if he crashes at this moment, he will fall to the level of work immediately below where the limb is normally closed. The crash will thus be without danger.

Det vil iøvrigt ses, at man kan anvende lemmen ved at anbringe den et andet sted end i et adgangsrum dannet i et stillads. Hvis dette stillads ikke har noget adgangsrum, 3o og den lodrette stige 5 simpelthen er anbragt ved enden af stilladset vinkelret på væggen 1, er det således tilstrækkeligt at vende lemmen 9o° i dens plan for at fastgøre den på den lodrette stige på samme måde som i fig. 1. Lemmen forlænger således platformen hen til den lodrette stige, når lem-35 men 14 er lukket, og spærrer for adgangen til stigen, når lemmen 14 er hævet.Moreover, it will be seen that the limb can be used by placing it elsewhere than in an access room formed in a scaffold. Thus, if this scaffold has no access space 3o and the vertical ladder 5 is simply disposed at the end of the scaffold perpendicular to the wall 1, then it is sufficient to turn the limb 9o ° into its plane to secure it to the vertical ladder in the same manner as in FIG. Thus, the limb extends the platform to the vertical ladder when limb 14 is closed, blocking access to the ladder when limb 14 is raised.

Det vil iøvrigt ses, at lemmen 14 og den faste del 13 5 142850 af lemmen kan fremstilles af et hvilket som helst egnet materiale, f.eks. af træ, og at de ligeledes kan være forsynet med en hvilken som helst egnet beklædning.Moreover, it will be seen that the limb 14 and the solid member 13 of the limb can be made of any suitable material, e.g. of wood, and may also be fitted with any suitable covering.
